Exercise is a kind of physical activity that increases
blood flow and heart rate beyond resting levels. Exercise profoundly affects overall health, and It keeps us away from lethal diseases and age-associated
deformities like heart attack, diabetes, osteoporosis, etc. However, people
suffering from a muscular disorder or mobility issues should consult their
doctors first.
In the past
few decades, due to globalization and the usage of modern electronic gadgets,
many people adopted a sedentary lifestyle which is the root cause of many
diseases like obesity, etc. Therefore, it is necessary to bring the importance
of Exercise to public attention.
In this article, I tried my best to explain the different types, pros, and cons of workouts and the science behind Exercise at the molecular level.
Five
Wonders of Exercise:
Exercise is essential for holistic health and helps us in myriad ways. Here I am discussing the importance of workout to reap its benefits.
- Reinforce Mental Health: Exercise improves mental agility. When we do aerobic or anaerobic Exercise, a rush of blood hits our brains. As a result, our brain releases neurotransmitters like endorphins, dopamine, and serotonin. Endorphins act as a blocking agent for the perception of psychological pain and give us a sense of pleasure. It boosts mood, reduces tension, improves cognitive abilities, and regulates the sleep cycle. In the meantime, dopamine and serotonin create a feeling of motivation and encouragement after Exercise. Hence, any form of physical activity helps people suffering from depression and anxiety.
- Slow Aging:
Aging is a
natural biological process where the body experiences physical deformity, poor
mental capability, and other age-related diseases. Exercise does not make you
look like your teens, but it reduces the chances of getting injuries and
dementia and improves the quality of life.
The reason behind aging is Telomeres, the repeating sequence of nucleotides at each end of chromosomes. It maintains genome stability by protecting it from enzymatic degradation and helps in cell division. Telomeres shorten after every replication. As we age, telomeres become so short that they reach the limit point where the cell can no longer divide. As a result, cell death or senescence occurs, and the tissue starts aging.
- Boost Cerebral Function:
Neuroplasticity
is a phenomenon in which the brain modifies its structure and function by
reorganizing neural patterns in response to a stimulus. Aerobic Exercise revs
up the rush of blood flow into the brain, which facilitates neuroplasticity by
increasing the production of a growth factor of nervous tissue called
brain-derived neurotrophic factor (BDNF), which promotes neurogenesis and
protects existing neurons.
Over time,
brain cells start to degenerate. Therefore, older people experience memory
loss, dementia, Alzheimer's disease, etc. Exercise staves off the risk of
neurological deterioration by releasing biochemicals that protect the brain
from age-associated memory loss.
Thus,
physical Exercise prevents the loss of nerve cells in the part of the brain
that is responsible for cognitive function. Exercise protects the brain from
neurodegenerative diseases, injury, and loss of cognition.
- Weight Reduction:
The prevalence of obesity has skyrocketed in the past two decades, and the
reason behind it is an obesogenic environment, a sedentary lifestyle, and poor
eating habits. If globesity does not manage, then it will create havoc all over
the globe.
Diet and Exercise are the key factors when it comes to weight loss.
Exercise helps build muscle mass and improves metabolism, which
ultimately helps
in the fat-burning process.
- Disease prevention:
A sedentary lifestyle plays a crucial role in the prevalence of many diseases like high blood pressure, heart disease, cancer, musculoskeletal disorders, and diabetes. Therefore, researchers suggest exercising six days a week to protect your body from chronic diseases. According to doctors, Exercise is a polypill because it contains many age-related detrimental diseases, boosts physical health, and improves mental health.
Consequences of Sedentary Lifestyle:
- Obesity
- Osteoporosis
- Cardiovascular Disease
- Hypertension
Main
Types of Exercise:
Aerobic
Exercise:
It is also known as Cardio. It is a slow to moderate-paced exercise in
which the body needs oxygen for glucose catabolism. It helps to
increase your heart rate, makes you breathe faster, and improves the
functioning of the lungs by delivering
oxygen to each cell.
Aerobic
exercises have countless benefits:
1. Burn
fat:
Diet plays a
primary role in weight loss. If your goal is to lose weight, then make sure your calorie intake is less than your energy expenditure, which means you have a calorie deficit diet.
Doing
aerobics would increase the transportation of oxygen to the cell for glucose
metabolism, which in turn gives us energy. After half an hour of endurance
training, your body utilizes energy from stored fats around your body.
2. Maintain
glucose level.
Hyperglycemia
(high blood sugar) occurs when the blood sugar level exceeds normal. If not
treated on time, it would eventually lead to ketoacidosis, a lethal disease.
Hyperglycemia happens when there is no insulin or ineffective insulin.
To absorb glucose,
your cells must be reactive to insulin, which signals the cell to utilize
glucose for respiration.
Exercise boosts insulin sensitivity by alleviating blood circulation in
the body. While exercising, our muscles use energy from
glucose, lowering the circulatory system's sugar levels.
3. Improve the Immune system:
Immune cells are an integral part of our defense system against
pathogens. Recent studies suggest that muscular contraction and
relaxation during Exercise enhance cytokine production, which
prevents the body from infectious diseases by activating other
immune cells. Even after 2–3 hours of intense activity, the white
blood cells remain in the circulatory system to ward off any
pathogen present in the
circulatory system.
Examples:
- Cycling
- Stair climbing
- Swimming
- Rope skipping
An Elliptical Bike is your go-to choice for gentle yet effective cardiovascular Exercise for weight loss. This fitness machine offers a low-impact exercise experience promoting enhanced physical health. Regular sessions on an elliptical machine can yield numerous benefits, such as boosting stamina and fortifying both your upper and lower body. Embrace the power of an elliptical machine to elevate your overall fitness and enjoy a rewarding exercise routine.
Anaerobic
Exercise:
Aerobic exercises are fast-paced workouts for short time intervals. They do not require oxygen. Instead, they utilize energy from muscles and stored fats.
1. Muscle Hypertrophy:
The size of
the muscles depends on physical exertions upon it. Muscles develop with intense
labor upon muscle tendons and ligaments during Exercise. When the muscle
fibers sustain an injury, our body releases proteins that repair damaged
skeletal muscle fibers. This process is called muscle hypertrophy.
Along with these proteins, muscles release certain hormones and growth factors, which enhance tissue growth and muscle development.
2. Boost metabolism:
Metabolism
is a biological process in which the body utilizes energy from the food we eat.
All the components in the food convert into energy, with the help of oxygen,
through cellular respiration.
Certain
factors like; age, weight, sex, and hormonal dysfunction, may slower your
metabolic rate, which means that your body takes more time to convert food into
energy.
Exercise helps in reducing body fats and ameliorating muscle mass. Muscle cells require more energy than adipocytes (fat cells), meaning muscle speeds up your metabolism and burn calories faster than fatty tissue.
3. Strengthens Bones:
With time,
our bones get depleted of calcium and other minerals. These minerals and
calcium are crucial for bone strength and health; these deficiencies weaken bones and increase bone fragility. Thus, the chances of bone fracture
become double.
Regular
workouts decrease the mineral loss from the bones and build muscle strength and
muscle mass, which protect bones and joints from fractures. It keeps your bones
dense and mitigates the risk of osteoporosis.
Examples:
- Sprinting
- High-Intensity Interval Training (HIIT)
- Mountain Climbing
- Calisthenics.
S
S Strength Training:
Exercises
like weight lifting and resistance training rev up your muscle mass and basal metabolic
rate (BMR), meaning your body burns calories even if you rest.
Consult your Practitioner before following any workout regime.
If you are suffering from back pain, fracture bone, or arthritis, then
These exercises would make your
condition worsen.
Pros
and Cons of Exercise:
The benefits
of Exercise outweigh its drawbacks. We already discussed some benefits of
Exercise, like regular physical activity improves sleep patterns, reduces the
risk of some life-threatening diseases, boosts the immune system, and improves
joint function.
Everything
has some positive and negative sides. There is some downside of vigorous
Exercise, which I mention below.
Exercise-related
Injuries:
Many people get motivated after watching a YouTube video or
reading blogs without knowing the consequences of high-intensity
exercises on their bodies. Many people start workout regimes
without fitness trainers, which results in backbone injuries or joint
fractures. Henceforth, for those having arthritis and heart disease,
high-intensity workouts are not recommended to them.
Muscle
Cramps:
Exercise-associated muscle cramps (EAMC) occur during or after
intense physical exertion. It is because of muscle strain and tear. Our
body feels discomfort and fatigue. Muscle cramps limit mobility
and affect daily routine. Moreover, high-intensity Exercise would
lead to muscle damage and fibrosis.
Heart
problem:
According to an old proverb: "Excess of everything is bad."
Therefore, exerting
too much pressure on cardiac muscle damage it completely.
According to one research, high-intensity workouts can increase the
chances of sudden heart attacks and could lead to ventricular
arrhythmia in individuals with implicit
coronary heart disease.
The benefits of Exercise outweigh the risks. Therefore, a moderate workout for a half hour, six days a week, is recommendable.
To
Make A Long Story Short:
Any physical
activity that alleviates your heartbeat and makes you sweat is good for your
health. The American Heart Association recommends a minimum of 30 minutes of
moderate Exercise daily.
A physically active regime has countless benefits for your physical and mental health. It boosts metabolism, lowers blood sugar, and weight loss, improves cognitive function, and more. This article aims to make people realize the importance of physical fitness for overall health. On the contrary, if you have conditions like arthritis, osteoporosis, and heart disease, you should consult your doctor before following any workout regime.
